The lower leg portion can rotate freely on the tie rod and is connected to the upper leg portion or to the tie rod and restrained from axial movement relative to the upper leg portion. The tie rod includes an annular flange located between the upper and lower leg portions so that substantially the whole of any forces applied downwardly to the tie rod or to the upper leg portion are transmitted to the lower leg portion through the flange.
